The spatial resolution of epidemic peaks.
PLoS Computational Biology, 2014 The emergence of novel respiratory pathogens can challenge the capacity of key health care resources, such as intensive care units, that are constrained to serve only specific geographical populations.

The Impact of Cross-Talk in a Flat Panel Detector on CT Image Quality
IEEE Open Journal of Instrumentation and Measurement, 2023 Spatial resolution and image noise are two aspects of image quality of an X-ray computed tomography (CT) system and are determined by the X-ray source, the detector, and mathematical operations for image reconstruction.

Investigation of the Spatial Resolution and Field of View with Change of Magnification in VRX CT [PDF]
Iranian Journal of Medical Physics, 2010 Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV).

3D spatial resolution characterization for volumetric computed tomography
AIP Advances, 2022 Spatial resolution is a key parameter that determines the smallest resolved scale in volumetric computed tomography. However, the evaluation process is typically confined within a plane, and tomographic resolution is usually treated as a two dimensional ...

Spatial Resolution of Coherent Cathodoluminescence Super-Resolution Microscopy [PDF]
ACS Photonics, 2019 We investigate the nanoscale excitation of Ag nanocubes with coherent cathodoluminescence imaging spectroscopy (CL) to resolve the factors that determine the spatial resolution of CL as a deep-subwavelength imaging technique. The 10-30 keV electron beam coherently excites localized plasmons in 70 nm Ag cubes at 2.4 and 3.1 eV.

Effects of spatial resolution on image registration [PDF]
SPIE Proceedings, 2016 This paper presents a theoretical analysis of the effect of spatial resolution on image registration. Based on the assumption of additive Gaussian noise on the images, the mean and variance of the distribution of the sum of squared differences (SSD) were estimated.

Investigating Suppression of Cloud Return with a Novel Optical Configuration of a Doppler Lidar
Remote Sensing, 2022 The full-width at half-maximum or probe length of the Lorentzian weighting function of continuous-wave Doppler lidars increases quadratically with the focus distance, which results in a deterioration in the spatial resolution of measurements.
